RPM usage

# rpm -ivh foo-2.0-4.i386.rpm

# rpm -i ftp://ftp.redhat.com/pub/redhat/RPMS/foo-1.0-1.i386.rpm

# rpm -i http://oss.oracle.com/projects/firewire/dist/files/kernel-2.4.20-18.10.1.i686.rpm

Used to install a RPM package. Note that RPM packages have file naming conventions like foo-2.0-4.i386.rpm , which include the package name (foo), version (2.0), release (4), and architecture (i386). Also notice that RPM understands FTP and HTTP protocols for installing and querying remote RPM files.

# rpm -e foo

To uninstall a RPM package. Note that we used the package name foo , not the name of the original package file foo-2.0-4.i386.rpm above.
# rpm -Uvh foo-1.0-2.i386.rpm

# rpm -Uvh ftp://ftp.redhat.com/pub/redhat/RPMS/foo-1.0-1.i386.rpm

# rpm -Uvh http://oss.oracle.com/projects/firewire/dist/files/kernel-2.4.20-18.10.1.i686.rpm

To upgrade a RPM package. Using this command, RPM automatically uninstall the old version of the foo package and install the new package. It is safe to always use rpm -Uvh to install and upgrade packages, since it works fine even when there are no previous versions of the package installed! Also notice that RPM understands FTP and HTTP protocols for upgrading from remote RPM files.
